What if we made it mandatory for all citizens over a particular age of [place country here] to own at least one gun, perhaps providing a government issue sidearm free of charge as well?
Perhaps we could go even further and mandate that the gun be visible (in a holster) at all times when in pubic. Some restrictions/exceptions may apply like requiring people to temporarily relinquish them before entering a courtroom.
How would these changes affect the culture of interest? Would you support such a policy?
